Extended Data Fig. 2: Wing and beak lengths across multiple generations.
Boxplot showing soapberry bug wing and beak lengths across multiple generations of Koelreuteria-associated brachypterous females. Panel (a) is a generational comparison of insect wing length between flooded (dark blue) and unflooded control sites (light blue). Model selection using linear mixed models (LMM) suggests that forewing lengths were longer at flooded sites in the three generations that followed recolonization (LMM: F(3, 205.1) = 10.80, P < 0.001; Supplementary Table 5). Panel (b) is a generational comparison of insect beak length between flooded (dark blue) and unflooded control sites (light blue). Model selection using LMM suggests that beak lengths were longer at flooded sites in the three generations that followed recolonization (LMM: F(3, 202.6) = 27.44, P < 0.001; Supplementary Table 14). In both panels, the red dashed line corresponds to Hurricane Harvey. Each ‘generation’ represents a 60-day block of time, which is equivalent to the maximum adult lifespan of a soapberry bug50. The upper and lower edges of the box indicate the first and third quartile, the midline indicates the median value and the whiskers show the 95% confidence intervals with dots as outliers. Sample sizes in grey within panels. Boxes capped with different letters are significantly different (Tukey’s test: P < 0.05, see Supplementary Tables 15, 22). There were no brachypterous insects present during initial colonization, so a boxplot for flooded post-hurricane insects was not included in either panel.
